To-all whom it may concern .7

Be it known that I, GOTTFRIED SOHNEIDERS, a citizen of Germany, and a resident of Heide, Holstein, German have invented certain new and useful improvements in Mineral- Oil and Carbohydroge'n-Gas Extracting Processes, (for which I have filed applications in Germany, Patent N 0. 305,7 94,

January 15, 1917; Germany, Patent No. 319,548, March 15, 1918; Germany, Patent No. 319,549, March 25, 1918; Austria, PatentNo. May 28, 1918 Hungary, Pat-' ent No. 78,398, June 3, 1918,; Rum'ania, Patent-No.- July 5, 1918;) and I do hereby declare the following to be a full, clear,

and exact description of the invention, such gaseous deposit with the aid of an air-dam having shuttable doors that is shifted into the deposit by hydraulic pressure. When all the oil and gas in the deposit in the neighbourhood of the air-dam has been removed, the'doors of the air-dam are opened and the rock is then pressed through the door, the air-dam being shifted forward-and the lining of the drive extended as the excavation work proceeds.

By the afore-descri bed process the rock is caused to yield up most of the flowing oil which it contains. But a certain portion of the existing bitumen will be retained by the rock in a manner similar to a sponge, WlllCll only yields up a certain surplus of the liquid it sucked up, Whilst the remainder secretes itself in the pores of the sponge and makes it damp. This residual bitumen envelops each single grain of sand like a thin skin and up to the present it was only possible to separate it from the sand by dislocating the latter and sending it to the surface, where it was boiled in water or broiled in closed vessels.

It is an object of this invention to provide means for subjecting the sand. which is damp with petrol to a preparatory process at the place Wherethe oil is extracted from the deposit immediately after the oil extracting process explained i'n the preceding paragraphs is concluded, and to separate the bitumen at the place of the deposit dur- 1ng the removal of the oil-bearing sand. To this enddetach the oil-bearin sand frtom the deposit by means of a hydraulic 1e I have'illustrated a preferred embodiment of my invention in the accompanying drawing, which is a vertical sectional view of an apparatus embodying my invention.

In the figure if indicates a pump whose pressure pipe 9 is provided with, a nozzle that is passed through the door of the end plate 03, or through a slit or a balljoint in the door, into the space it for the purpose of dislocating the sand by washing it away.

The li uid squirted through the nozzle con-- sists 0 cold, or preferably hot, water or solutions of salt such as a lye of magnesium chloride or the like. By the mechanical thermal and dissolving action of the jet,

Grimm-application filed September 2, 1919, Serial No. 321,275. Divided and this applicationfiled Aul and on account of the friction of the grains of sand against each other, the bitumen is immediately separated from the sand'at the place where it is removed from the deposit.

The slimes consisting of sand, bitumen and water or another liquid are drawn off from thespace 72, through a suction piper by an elevating pump and forced through a pressure pipe 12 into a collecting pit w (blind shaft or Water-hole) in which the sand settles at the bottom, the squirting fluid at middle height, and the oil at the top. It isadvantageous to arrange several collectingpits 20 so that onemay be emptied whilst from another squirting fluid is taken through a pipe 00 and oil through another pipe, the squirting fluid being returned by the pump 71 to the place of excavation, whilst theoil is sent to' the surface through a pressure pipe 2. When one pit is filled and another 1s emptied and cleaned, the actions of the various suctions and pressure pipes are re: versed, so that the empty pit is filled and the fullcollecting pit is emptied and cleaned.

To obtain a still more perfect .separation of the' bitumen from the sand, the pipe 4) through which the slimes are drawn from the space h, may be heated by an enveloping steam pipe 1' through which steam, engine gases or any other heating agent may be sent.

Thus'-in 'using 'my new process it is not flnecessary"toy'send the sand to the surface.

' hering The sand can be freed of the bitumen adto it immediately 'after it is dislodged'froin the deposit, and used for filling v hollow spaces in the 'mine and for Caulking joints.

I claim:

1. The process of removing oil-bearing sand from :its' deposit and of simultaneously subjecting it to an oil separating treatment consisting ,in dislodging the sand from its deposit by a jet of fluid so that by the action 'of the jet and by the friction set up between the grains of sand, said grains-are freed of the bitumen which adheres to them.

2. The process of removing oil-bearing sand from its deposit and of simultaneously subjecting it to an oil separating treatment consisting in dislodging the sand from its deposit b a jet of hot fluid so that by the heat and y the action of the jet, and by the friction set up between theigrains"of sand,

these latter are freed of the bitumenwhich adheres to them. 2 l

3. The process of removing oil-bearing sand from its deposit andof simultaneously subjecting it man oil separating treatment consisting in dislodging the sand from its deposit by a jet of fluid so that slimes com posed of sand and the said fluid are formed,

and in sending the said slimes through a heated pipe, so that by the action of the jet,

the friction of the grains of sand against each other, and of the heat .derived'from the sand is neutralized and oil made free to col- In testimony whereof I aflix my signature v in presence of two witnesses.
